Description
The present invention relates to a kind of optical recording and reproducer, particularly relate to a kind of optical recording and reproducer with leading axle support, wherein, the established angle that is used for the leading axle of direct light pick device can be easy to adjust.
Optical recording and reproducer are to be used for reappearing the device that is recorded in optical recording media information, and recording medium is hereinafter referred to as CD, for example compact disk, digital picture CD or videodisc.The CD that is loaded on the turntable in optical recording and the reproducer rotates the groove detected light information that no pick device forms from CD according to predetermined speed.
Optical take-up apparatus has a semiconductor laser to be used to launch laser, photosensitive reception diode is used to receive the laser beam from CD reflection, object lens are used to focus on by the laser beam of the optical track of optical disc surface or mark scattering or diffraction and a driving mechanism and are used for focusing on and the tracking object lens.Optical take-up apparatus radially carries out rectilinear motion along it along guidance axis above CD.Here, for the error of eliminating or reducing to write down and reappear, the rectilinear motion of optical take-up apparatus should be accurate.Therefore, in the manufacturing of optical recording and pick device, the position of leading axle and established angle should be accurately definite and fixing.
Fig. 1 is that the axle of the part of a kind of existing optical recording of expression and reproducer is surveyed synoptic diagram.Optical recording and reproducer 10 comprise base plate 11, the turntable 12 that is used for the loading optical disk (not shown), be used to drive the drive motor 19 of turntable 12, on base plate 11, carry out the optical take-up apparatus 15 of linear reciprocating motion, optical take-up apparatus drive motor 16 and be used for converting the rotational motion of optical take-up apparatus drive motor 16 to straight-line leading screw 18.In a side of optical take-up apparatus 15, formed a flank of tooth (not shown) that meshes with leading screw 18, optical take-up apparatus 15 is directed along leading axle 13 by the rotation of leading screw 18.
In addition, optical take-up apparatus 15 comprises a tracking coil (not shown) and a focusing coil (not shown).Tracking coil is finished following function, be may command make object lens radially in preset range, moving in the optical take-up apparatus along CD, focusing coil is finished following function, and the distance of promptly controlling between optical take-up apparatus 15 and the optical disc surface is in the predetermined scope it.
As shown in Figure 1, optical take-up apparatus 15 comprises the through hole 15a that guidance axis 13 passes, and guidance axis 13 is supported on the base plate 11 by bearing 14.In order to make the through hole 15a that forms on the guidance axis 13 alignment light pick devices 15, the position that is fixed on the bearing 14 on the base plate 11 should be accurate.But in above-mentioned bearing support structure, the horizontal angle of guidance axis 13 is not easy Be Controlled.Promptly when the angle of guidance axis 13 little error occurs owing to the error in manufacturing or the installation process, can correct it without any way.
Therefore the purpose of this invention is to provide a kind of optical recording and reproducer with leading axle support, wherein, the established angle that is used for the leading axle of direct light pick device can be easy to adjust.
For achieving the above object, provide a kind of optical recording and reproducer, having comprised: a base plate; A turntable that is used for loading optical disk; Optical take-up apparatus with the through hole that is used to guide; Insert the guidance axis that through hole is used for the guide lights pick device; Be rotatably mounted to the supporting member on the base plate, its side forms a patchhole that is used to insert and support guidance axis; The one group of projection that forms in the patchhole is in order to the outer surface of butt insertion guidance axis wherein.
The preferred hexagonal section of guidance axis support, patchhole are circular, and projection is a semisphere, and being disposed in the patchhole according to 90 degree.
More preferably, the diameter of an imaginary circle that is formed by the summit of said projection and the outer circumference diameter of described guidance axis match.
Above-mentioned purpose of the present invention and advantage will be clearer in the description of a preferred embodiment of doing below in conjunction with accompanying drawing.Wherein,
Fig. 1 is that the axle of the part of a kind of existing optical recording and reproducer is surveyed synoptic diagram;
Fig. 2 is the synoptic diagram according to the guidance axis support of optical recording of the present invention and reproducer employing;
Fig. 3 is the front elevation of guidance axis support shown in Figure 2.
According to the present invention, the basic structure of optical recording and reproducer and shown in Figure 1 similar.Promptly, optical recording of the present invention and reproducer have base plate 11, the turntable 12 that is used for loading optical disk, be used to drive the drive motor 19 of turntable 12, on base plate 11, carry out the optical take-up apparatus 15 of linear reciprocating motion, optical take-up apparatus drive motor 16 and be used for converting the rotational motion of optical take-up apparatus drive motor 16 to straight-line leading screw 18.Optical take-up apparatus 15 has one group of through hole 15a, and guidance axis 13 inserts through hole 15a in order to guide lights pick device 15.
With reference to figure 2, wherein the parts corresponding to Fig. 1 adopt identical label to represent, wherein, it is polygon or circular post that guidance axis support 21 of the present invention is designed to the cross section.Here, in a side of post, be formed for inserting the patchhole 22 of guidance axis 13.In the bottom of guidance axis support 21, formed a bolster 24.Combine rotationally by bolster 24 between guidance axis support 21 and the base plate 11.Preferably, guidance axis support 21 is designed to the sexangle cylindricality.
With reference to figure 3, in patchhole 22, formed one group of projection 23.Preferably, projection 23 is designed to semisphere.The periphery that is inserted into the guidance axis 13 of patchhole 22 contacts and is supported by the summit of projection 23.Therefore, the diameter of a circle that connects the summit formation of each projection 23 should coincide with the external diameter of guidance axis 13.
In one embodiment, projection 23 is formed in the circular patchhole 22 at interval with 90 degree.Therefore, guidance axis 13 at a contact condition lower support on the summit of projection 23.For guidance axis support 21 moving on base plate 11, formed a screw thread 24a in the end portion of bolster 24, a nut 29 that is positioned at the bottom of base plate 11 is connected in this, thereby guidance axis support 21 is pivotally connected on the base plate 11.
In the manufacturing or repair procedures of optical recording and reproducer, occur not having aligning if detect the angle of guidance axis 13 with independent device at surface level, the operator only need rotate guidance axis support 21, just can more accurate drift angle.That is, when the guidance axis support 21 of Fig. 2 rotated by direction 27, guidance axis 13 can be corrected in the angle of surface level, shown in the direction 28 of Fig. 2.Because guidance axis 13 is supported on the peak of projection 23, as long as guidance axis support 21 rotates in a smaller angle, the mobile bending that can not produce of guidance axis support 21 with respect to guidance axis 13.
According to optical recording and the reproducer with support of the established angle that is used to control guidance axis of the present invention, the angle of the surface level of guidance axis can easily be controlled.Therefore, optical take-up apparatus can accurately be guided.
Should be understood that the present invention is not limited only to illustrated embodiment, those of ordinary skills can make many change and changes that belong to the scope of the invention.That is, according to present embodiment, a circular patchhole is formed on a side of hexagon prism, and spherical protuberances is provided with by the interval of 90 degree.But, can at interval 3 projections be set according to 120 degree, perhaps use a tetragonal post to substitute hexagon posts.
